Oil Leak

Good day, I bought a vehicle not a month ago and it has an oil leak. The roadworthy certificate off cause does not indicate this. I bought the Ford, but my husband signed the \contract"that there is no warranty on wear and tear.I have seen this document for the first time when it was mailed to me. We are married on ANC. The oil leak was noticed when we got home from the dealership. We live in Secunda and I bought in Nelspruit. I assume it is because the oil was thinner with driving the distance and that is why its noticed only later. I have taken out insurance and the radiator has to be replaced. I asked for the oil leak also to be repaired"
